Title: Process for controlling end-point density of sintered uranium dioxide nuclear fuel bodies and product
IPC: G21C3/62
Filed: 1973-10-16
Abstract: A process for controlling the end-point density of a sintered uranium dioxide nuclear fuel body and the resulting product. Uranium dioxide powder having a size ranging up to 10 microns is admixed with a precursor to uranium dioxide, such as ammonium diuranate, having an average agglomerated particle size ranging from about 20 microns to 1 millimeter and the mixture is formed into a pressed compact or green body. The precursor to uranium dioxide has a density lower than that of the uranium dioxide powder and is used in an amount which results in discrete low density regions in the green body which range from about 5% to 25% by volume of the green body. The green body is sintered to decompose the precursor and produce a sintered body having discrete low density porous regions which reduce the end-point density of the sintered body by at least 2%. The sintered body has an end-point density ranging from 85% to 95% of theoretical.

Title: International combustion engines
IPC: F02D41/12
Filed: 1976-07-05
Abstract: In order to retard the closing movement of the throttle valve (2) without significantly impairing the running of the engine, this closing movement is controlled as a function of the vacuum upstream and downstream of the throttle valve (2). In doing this, an air feed device automatically feeds additional air to the feed duct (1) downstream of the throttle valve (2) when the vacuum there falls sharply. This device has an additional air inlet (18) arranged downstream of the throttle valve (2), which inlet is connected by way of an inlet line (19) to a control valve (20) preloaded in the closing position. The latter is designed so that in the event of a sharp increase of the vacuum on the inlet (18) it rapidly opens in order to immediately counteract this increase by an additional air feed.

Title: Improvements in or relating to electronic control systems for recording and/or playback apparatuses of the reverse type
IPC: G11B15/02
Filed: 1979-06-09
Abstract: In an electronic control system for a reversible tape recording and/or playback apparatus, a detector 1 produces a logic 0 or 1 output according to whether the tape is stationary or moving and is connected to a logic block 2 giving a 1 or 0 output according to whether the tape stopped while before it was moving or stopped while before it was stationary. At each 1 to 0 transition of the block 2 output, a monostable 3 produces an output pulse which momentarily de-energises a relay R1 to effect automatic reversal of the tape drive direction. In a first state of a function programmer 7, switches 4 and 5 are open and the tape is continuously reversed at each end. With programmer 7 in a second state, switch 4 is closed, 5 open and 6 at I so that at the first tape end, relay R1 reverses the tape direction, whereas at the second tape end relay R1 reverses the tape direction and, due to divide-by-two circuit 8, relay R2 ejects the tape cassette and transistor 24 turns off motor 23. In a third state of programmer 7 the cassette is ejected and motor 23 turned off at each end of the tape. A tape head position- sensing switch S4 (Fig 3) prevents cassette ejection before the head has been extracted therefrom. Detector 1 may be of capacitive type (as in application no. 7907419).
